Methods and systems for transmitting an image with thumbnail data
摘要
說明書
It is noted that this particular scan script configuration is exemplary only, and uses particular data that has been found, in practice, to reasonably balance the size of each respective scan with the quality that results from rendering the scan in conjunction with previous scans. For instance, the first scan that produces a progressive thumbnail tends to provide a relatively high amount of information in a relatively low amount of data. The quality is not sufficient for this information to represent a mid-quality image, but it is sufficient for use as a thumbnail. In practice, the low-quality scans tend to bring in about half of the image data (about 36-67%, with an average of about 48%), whereas the mid-quality scans tend to bring in 56-81% of the image data, with an average of around 66%. In many cases, the mid-quality images are indistinguishable to a human from the original full-quality image.
